 lapides ab Oxonio dissita, {Bobart) Morison, Hist. Ox. iii. 580, 1699.

5. Loddon. Windsor Park. Sunninghill Wells, Lond. Fl. 293. Near 

 Loddon Bridge, Rev. Dr. Lang, 1889, but I have not seen specimens. 

 In the Bobart Herbarium at Oxford specimens of DnjoiAeris Thehjpteris 

 and D. montayia (Lastrea OreoiJterifi) are mixed, so that Bobart may have 

 intended the latter plant, which I have seen at Wytham ; possibly he 

 may have found both species, but I have not been able to find 

 Thehjpteris there or near Loddon Bridge. 



D. Thelypteris is recorded only for Surrey and Hampshire of the 

 bordering counties.
